“…The thermal behavior of the fuse link during steady-state conditions was analyzed in [8], when different types of notches are applied using 3D FEM software. In [9], an FE model of a fuse was used to analyze the influence of harmonic content and harmonic frequency by thermoelectric coupling simulation. In [10], an FEM model of a medium voltage fuse was used for thermal analysis.…”

This paper describes the identification of the thermal parameters for the high breaking capacity low-voltage NH gG fuse. For the process of parameter's determination, a 3D numerical model of the fuse is used together with the measured temperature on the fuse and differential evolution (DE) as the powerful optimizer for optimization problems. DE's main task is to reduce the difference between the measured and calculated fuse temperatures. The classic DE algorithm is compared with three improved DE algorithms that have a reduction of the population size during the optimization process. The results of all four algorithms are compared, and the most favorable choice of algorithm is given for such temperature coefficient calculations. The fuse model is appropriate for the calculation of the fusing temperature, according to the excellent agreement between the measured and calculated fuse temperatures.

“…The thermal analysis of a medium voltage fuse by the finite element method is described in [21] where the model has been designed and simulated under various conditions of ambient temperature with the Cosmos software tool. In [22,23], the effect of the current harmonics (with different THD) on the fuse thermal operating conditions, was studied using the software ANSYS. A mathematical model of the fuse time-current characteristic is presented in [24].…”

In many industrial applications high breaking capacity (HBC) fuses are used to protect electrical installations against overcurrents, especially in the power distribution network. At high rated current, HBC fuses have more parallel fuselinks mounted inside. The technological and mounting processes of the fuselinks inside the fuse results in an asymmetrical current distribution through the parallel fuselinks. In this article a model of a high breaking capacity fuse using two parallel fuselinks is proposed. The influence of electric current, cross-section of the notches, distance between notches and current imbalance through fuselinks on the maximum temperature rise of both fuselinks, has been investigated. Also, a 3D thermal model for the same HBC fuse has been developed. The temperature spread into the fuse and its elements has been obtained. In order to prove the validity of the mathematical and 3D model different tests have been considered. The experimental, simulation and computed results give similar values and it results that this model can also be used for fuses with many parallel fuselinks and it permits the design of new fuse elements with optimal thermal distribution.
